IMPROVEMENT lN SHINGLE-MACHINES.

To enable others skilled in' the art to make and use my invention, I will now proceed. to describe its construction and operation.

lp'rovide a suitable frame or bench A A A, and arrange upright corner-posts Q Q, to which I attach vertical slides Z Z to keep the bolt-carriageG Gin proper position while ascending and descending by the saw.

I provide the usual set works, which by the set-shaft P. The shaft P is actuated by the set-rod L, in connection with the ratchet'S and the screw-collars b and 0, together with the stop (I. The rod L is'connected with and hangs from the ratchet S onthe carriage, and rises and falls,'therefore', with and attach. it to a rod, g, fig. 1, in the under side of ,I provide two shafts, F l, with gear-wheels a n and kit, fig. 3, at their respective ends-n n operating in connection with the intermediate g'ear-wheell, and It It, fig. 3, operating in connection with the racks e c, fig. 3. I I

I provide for-throwingthe oogwheels a n and 1 into or out of gear by means ofthe lever N and combined or attached lever O, figs. 1 and, 2, in connection with the rods s s, fig. 2, and the movable boxes t t.

I provide a shingle-flipper, U, fig. 2, with arms or prongs p p and the arm or lever 10, which is operated are operated a projecti g P f E by the long hook T, attached to the bolt-carriage O,

'. I provide a set ring, R, fitting on the shaft E, and set.in' placeon the shaft by means of the set-screw x, In operation the power is applied to the pulley D and shaft E. The set collar R is fastened firmly in lace on the shaft and bears against the box 3 thus preventing the saw from vibrating. The belt H transmits motion to the shaft G and gear-wheel 1, and the wheels n narethen brought into gear with the wheel 1 by the movement at the lever N at the back of the machine or the same object is attained by the use of the longv lever O, which extends along the end and to the front of the machine. The revolution of 1 causes a n to revolve in opposite directions, and It It, being on the p same shafts, respectively revolve 'in corresponding di- Figure-2, sheet N o. 2, is a perspective view of the 'rections with 'a a. I

The spur f-in the arm J runs on the right-hand side of the guide c, fig. 3, as shown in the drawing, and forces @the" rack c to engage'with the gear-wheel k, and this carries the bolt-carriage up by the face of the saw. As

the carriage rises the rod L slides in the stopcl until the coll-arc comes in contact with. (Z and causes the rod to draw upon the ratchet S and revolve the set-shaft P, which regulates the set works by the usual cams, as can be seen at u, so that when the carriage comes to the top of the saw the bolt is set over for another shingle. At this moment the spur f arrives at the top of the guide '0, fig. 3, and is instantly thrown to the opposite side of c by the spring r, This causes the rack c to engage with the wheel 1;, and the carriage is driven downward. As the carriage ascends the hook T engages the armor lever w of the shingle-tipper U and lifts it up, thus tipping the prongs p over away from the saw and onto the table; in this way the shingle sawed in the previous descent of the carriage is tipped out of the way of the succeeding shingle. As the carriage descends the weight of the lever 10 causes the prongs to tip back against the saw, and they are thus brought between the saw and each shingle as it is sawed.

The coil-spring M is attached to the frame A, and the cord X passes around the box of the spring and is fastened to the carriage sothat, as it descends and the cord is-drawn out, the spring is coiled up and exerts a lifting force upon the carriage, while the spur f, fig. 3, is passing the lower end of the guide 1; and the arm J is being transmitted from the action of the wheel k to engage with It. It is here that the spring is peculiarly serviceable in giving the carriage a quick start upward and preventing any hesitation in the movement of J. while being transferred from its eugagement with It to its engagement with It. When the carriage descends the collar-,l),'on the set rod L, comes in contact with the stop (I and arrests thefurther descent of the rod L. This pushes the ratchet 'S upward and backward until the spring-pawl contained in S engages with the ratchet-wheel a, fig. 4, and is thus preparedto revolve the set shaft 1? as the carriage again ascends.

The shaft P is provided with a double cam, u, at each end, and as the shaft revolves one end of the cam engages the hook of the latch B and depresses it, thereby withdrawing the spur afrom the rack "1?", while the other end of the cam engages the rack P and throws it forward. 'Atthis instant the cam leaves the latch c", and the spur uf'f enters the rack .P" in.

. which enable it to be moved in severalv directions toenough to regulate the latch and cause the spur a enter the rack at exactly the right instant, thereby n suring a uniform thickness to the shingle so far as any movement of the set works affects them. By ref-' erence to the drawing it will be seenthat if the screw 0,, fig. 1, he loosened in the slot 1), then the latchholder A can be moved up or down on this side, throwing the latch a trifle forward or backward, and the reverse may be accomplished with af I)", while byf loosening both screws the latch-holder may he moved up or down, as desired. I I

In order to provide againstthe vibration ofthe saw in either direction, I fix a permanent ring or collar, W, on the end of the shaft; or, if deemed necessary, this may be a set collar, so that when the shaft is crowded forward the collar bears against the outside of the box 3 and the set collar It is then adjusted to bear against the inside end of the box and set firmly in place by means of the set-screw x, thus providing a hearing or shoulder against each eud. of the box. Quite'a slight vibration of the sawcauses a difference in the thickness of the shingles, thereby lessening their market value.

The arrangement of the lever gear-wheels a ainto or out of gear with '1 while standing' at the opposite side of the machine; for by pressing on the end of O, fig. 1, at 'd, theother end of O, at d, fig. 2, is thrown forward, andat the same time the lever Nis thrown forward, pressing the sliding boxes t it together by means of the connecting-rods s s, and thereby carrying thegear-wheels a a into gear with the wheel 1, which causes a a to revolve in opposite directions and carry the carriage up and down alternately ,byactingon the arm J.

The arm J is attached to the rod 1 by a strap, 7:, which passesover the rod 9 and down the side of the should be- N in connection with the rod and lever 0 enables the operator to throw the l hold the strap h against the arm J, and the gib is held in place by the keyj, so that the whole maybe easily detached from the carriage at pleasure, for repairs or otherwise.

' By hanging arm J like a pendulum it is always in .equipoise, and easily shifted by the force of the springs into engagement witheither of the pinions, the same degree of force moving it in either direction.

By means of the adjusting-wedge it has a slight rangeof vertical adjustment, so that in any casual change of the relative position of the teeth of the racks and piuions they may be made to engage with certainty. By means of the strap, wedged key,'and gib, the arm is readily. removable at a moments notice, for repairs, shipment of the machine, &cl, and as readily replaced.

Eor 'conveuience in changing or removing the saw I shrink a collar" onto .the end of the shaft and'turn it up true. I then fasten my saw to the face of the collar without passing any part of the shaft through the saw. This allows the saw to be removed without unshipping the shaft.

' Collars have been shrunkonto shafts, but they have been used in such a manner as to be just the reverse of my method, and to necessitate passing the shaft through the saw to hang the saw to the collar, and

also to necessitate unshipping the shaft to remove the saw; in other words, I turn a face on the collar on the outside from the shaft, instead of on the inside toward the shaft.

I do not claim the carriage nor the movement of the carriage, nor anything conflictiugwith the Eva-rt-s patent, having purchased of Mr. Evarts the right to use his invent-ion so far as is necessury-tbr the coustruction-and -use of my machine; but- XVhat I do claim as my invention, and desire to secure by Letters Patent, is--.'
